Sensory receptor

A Sensory receptor is a structure that reacts to a physical stimulus in the environment, whether internal or external. It is a part of the sensory system which includes the sensory neurons, neural pathways, and parts of the brain involved in sensory perception.

Types of sensory receptors[edit | edit source]

There are several types of sensory receptors based on the type of stimulus they detect:

  • Thermoreceptors: These receptors respond to changes in temperature.
  • Photoreceptors: These receptors respond to light and are found in the retina of the eye.
  • Nociceptors: These receptors respond to pain or damage to the body's tissues.
  • Chemoreceptors: These receptors respond to chemical changes in the body.
  • Mechanoreceptors: These receptors respond to mechanical pressure or distortion.

Function of sensory receptors[edit | edit source]

Sensory receptors function by receiving a stimulus and converting it into an electrical signal. This process is known as transduction. The sensory receptor first detects the stimulus, then creates an action potential that is sent to the central nervous system for processing.
